jfl. .ff/' 'whom it muy concern:

' vknown that I, finnmn J. '.KNOX, a tir/.en oi the United States, residing at abois, in the county of Clearfield and State construction in which the center of gravity of the tank is gotten at the lowest possible point relative to the rails; and the provision ci: a car of' the character specified of simple, rigid construction with tl-iedratt and center sills in alinenient to takecare of and distribute Aihe stress applied tonthe draft sill. Certain embodiments of the invention are illustrated in the accompanying drawings,V l

the use or a casting oit' appropriate forni.

whcrein- Fig. l. is a partial plan View of the luider i framing of the ear, Fig. 2 is a partial side elevation and partial section through one end of a car built in accordance with my 1nvention, Fig. 3 is an end elevationV ot the car, Fig. #L shows twopartial half sections,

the right hand half of the igure being .taken on the line lY--IV of Fig. 2, and the iett" hand. portion on the line V-IV of Fig. i2, Figf is a plan v1e\v oi a modified nnih training construction, Fig. 6 is a partial longitudinal section through a car having the underiraming of Fig. 5,'Fig. 7 is two-part view showing at the right hand portion an end elevation of the car, and at is lett hand portion a section on the'line lll-VII ot' Fig. (3, Fig. 8 is ay sectie-n on the line 'VH1-VIH of Fig. 5, Fig. 9 is a plan view oi? a inodil'ied underfraining eonstruction, Fig. .l yis a longitudinal section through a car having underlraniing as in Fig. i), and Fig. ll is a two-part View, the right hand portion ofthe iiguie being a .tion taken on the line XI-Xl of Fig. 10, left hand portion being a section taken v'he line IKT- XF of Fig. 1.0.

in its preferred embodiment the car coinprises a pair of trucks together with a tank l; .ing a full cylindrical central portion and end pin-tions of substantially the same horizonai dimension as the central portion, but having their bottoni sheets depressed in order to provide spac'e for the trucks and that part of the underframing carried thereby. This arrangement gives a tankjof the best type available, that is, substantially cylindrical throughout, and one which at the same time may .be placed with its center of gravity very close to the ground, since the recessed sheets at the ends of the tank provide a space for the trucks, thus permit-` ting the bottom of the tank between the inner wheels of the truck to project' down to a level approximating that of the a'Xles of the wheels. This arrangement renders the use of a tank of relatively large diameter "sfpracticable, without making the ear topheavy. In its preferred form my invention contemplates the making of the re-curved sheets at thebottonls of the end portions of the tank integral with the draft sills and body sills, and the making of a portion" of such sheets act as a segmental head for the center portion of the tank lying between the Wheels, suoli object being accomplished by Referring iirst to the construction as illustrated in Figs. l to 4,1 is the center portion of the tank, which as heretofore indicated is of full cylindrical cross section, while 2 is one ofthe end sections of the tank which would have the saine cross section as the portion l if it were not for the use of the depressed bottoln sheet 3. ]Bottom sheet 3 constitutes a portion of a casting, the inner end 4 of which (Fig. 2) constitutes a segmental head or closure for that portion of the tank having the full cylindrical cross section, As indicated in Fig. 2, the portion or sheet 4 is provided with-a ilange 5 to which the Sheet G of the center portion ly of the tank is riveted.

yAlsointegral with the plate 3 is the transverse body bol ster 7, such bolster being made of any approved contour and opposing the` truck bolster 8 (Figs. 2 anda). Also integral with the same casting of which the sheet 3 and body bolster 7 constitute a part, is the draft sill 9 which extends longitudinally of the car at its center, such draft sill being of the cross section indicated in Fig. 4. The edges of the sheet 3 are perforated as indicated in Figs. l and t, and are secured by rivets to the parti-cylindrical shell. of sheet metal, in the manner illustrated.

It will be understood that the construction ,at the other end of the ear is the saine as .that above described, and that the right hand end of the center sill is connected to the underframe casting at such end of the car, inthe same manner as that illustrated in Fig. 2. This center sill l0 may be constructed in any desired manner, and is arlll' ranged in ali nement with the two draft-sills il, so that the two draft sills are mutually supiliiorted. ln order toeifectively secure tbe center sill l to the ea ig of which the plates 3 and 4i form a part, suoli casting is.

scribed as illustrated in figs. l-'to fl is al The eoi'istruction most advantageous one. permits of the retention of the cylindrical form, while at the same time permitting the placingv of the center line of the tank at a minimum distancev from the ground. The tank can be made of larger diameter than has heretofore been possible, the only limitation being that the bottoni plate G must be at a sullioient distance above the road bed to avoid interference therefrom.' lt will lbe seen that this structure is possible .by reason of the fact that the segmental head 1 is placed to the inside of the inner pair of wheels l2, thus permitting the upper portion of the tr ck and wheels to .lit up inside the space provided by using the re-eurved or depressed sheet 3. The making of the recurved plate 3, the body bolster, the draft sill, the segmental head and the splice memf ber 1l., all in one integral casting is also an advantage because of the cheapness of the construction and because of its great rigidity. @tirery advantages of the construction will be readily apparent to those skilled in the art. l

Figs. 5, G., and 8 illustrate another modilieatio'n in which tbe recessed portions at the ends of the tank are provided with sheet 'inet-al closure plates 1.3 (Figs. and T), thus calling for a modilieatioi'i ofthe underfram` ing indicated in if wherein the east plate irl: is made of tbe skeleton form illustrated instead of boing a continuous plate like the plate 3 in Fig. l. The cast member 14.- eomprises a body bolster l5, a. draft sill 16, a segmental head l?, and a splice member 18, substantially, similar to the correspond-- ing,l parts the construction of liigs. l and 2. The center sill 1.9 is similar.' to the sill l() of Figs. l. and 2, being riveted to the splice member li in the same manner as in tbe construction of l'igs. Ll and il.

Figs. Si, l0, andjll illustrate a moditication' of the invention in which a draft sill 20 built up of conimcreial sections, and a body nected to tbe draft sill and-the second of which is connected to the center sill 26. The general arrangement and Aother details of construction not above referred to, are suband 2 and and 6. Many other modifications might obviously be made without departing from vtbe fundamental features of the invention as illustrated in the three types of construction heretofore described. 7l5
